Won’t let me post anything

I was going to post a picture and when I clicked publish, it said “invalid response” so I deleted the little description I had and it still said invalid response!! I gave up and just tried a different picture and the same thing happened. No matter what I do, it doesn’t let me post anything! ?? i would give this a .5/5 because Recolor deserves it but I can’t because it’s not an option.
